The common steel bar mechanical connection mode is to sleeve a steel bar connector on the outer sides of two steel bars, then radially extrude the steel bar connector or axially extrude the steel bar connector through corresponding steel bar connection tools, so that the steel bar connector deforms and is meshed with the two steel bars to be connected, and the purpose of connection is achieved.
In order to improve the working efficiency of the mechanical connection mode of the steel bars, various types of steel bar connection tools exist in the market at present, and the existing steel bar connection tools mostly adopt a pull cylinder structure.
